Do you think that if they might not otherwise conform to my feet through my skating alone that if i get them heat molded it would help the breaking in process?
One heat mold won't break them in. I can't be sure for your particular boots, but 5 or 10 heat molds might be a good start. If you pay a pro to do that, it will take non-trivial amount of money. Too many heat molds, and they will break down.
I think you should just accept that boots that stiff will virtually never break in. You have to make them work and be reasonably comfortable at the current degree of stiffness. So if they aren't comfortable when you try them on, and you aren't willing to modify your boots big time, they may never be. I've heard it's different if you were doing triples - then they will eventually break in. I have no experience with doubles - maybe, after a few years, doubles will break in the boots. But you say you aren't there just yet.
With a really snug fit, and very stiff boots, there is only so much modification you can do. E.g., if the boot is too thin or not deep enough at some part of your foot especially around your toes, you can only stretch the leather so much there, even if you heat mold. (In fact, heat molds mostly undo stretches, so you have to re-stretch after heat-molding.) You can get a little extra room by removing the insole, and making your own that are much thinner - but the amount of space you gain that way is limited.
There is a possible psychological here. Because the boots are so high level, they could last you virtually forever. So if you buy them, are unhappy, but you feel you have to wait for such an expensive purchase to break down before you buy a replacement that makes you happy, that might never happen.
I've met a few people who flew internationally to to get fitted (or even just sharpened) by a particular skate tech, or to go to the boot maker's factory store. The flight can be even more expensive than the skates themselves...
Australia is a big piece of land. Is there really no skate tech in the big towns (like Sydney) who knows what they are doing? Perhaps your coach, or another local coach, would know. Also, boot makers can be called, and asked for advice on what skate techs to use. My mental picture of Australia is based on the Crocodile Dundee movies: I imagine you slogging through the mud, fighting off a crocodiles, and bandits, for days, and paddling the last few hundred miles on a surf ski, all to reach the nearest decent pro shop.
Hopefully, it isn't quite that bad! But even in the U.S. and Canada, reasonably serious skaters often drive 6 or 7 hours each way, or who fly, to get to a favored boot tech. (Local skaters often carpool to do it.) When it comes to something that can cause you pain for years, or damage your feet, that isn't that big a deal. A bad skate fit can do exactly that. Maybe you just haven't thought to drive or fly that far
within Australia yet?
If you can get good results from whatever fitter you use, that's really great. If all else fails, I have a web page on methods of modifying boots. E.g., it's actually reasonably easy to modify insoles with athletic tape, or trace your old one on a piece of foam, and cut it to shape in a 3D fashion. Most of what it takes is patience, an analytic mind, and a willingness to experiment. My most recent ones were cut out of a $7 (USD) foam camping pad - not ideal, because they don't last forever (they eventually squish down and change shape), but it's cheap, conforms well, and is skin-safe - and if you make a mistake, a 6' camping pad has room for lots of retries.
A lot of people on this board won't do that sort of thing. A lot of them instead buy several pairs of commercial insoles and "orthotics" (more or less the same thing). Some of them get lucky, but a large fraction, possibly most people, won't happen to fit a particular non-custom insole or orthotic, even if they buy one that is a heat molded. BTW, the cost of an insole or orthotic has little bearing on how well it fits - you are mostly just filling space, and that needn't take more than several dollars. The heat moldable orthotics do cost more money - but even they don't work for everyone.
