My personal opinion, based on your info is; "No"! This would not be the wise choice for an upgrade right now. You would see a greater benefit from spending that same funding on various other upgrades.
Front Mounts are entering into the more serious racer territory, and are often overkill, as in your case. I have recently purchased a used CAS V2 FM, but, I intend on running 10's in the coming year. Per your current setup, and even taking into consideration a future turbo upgrade, I think you'd benefit further from getting someone to port your heads, or even buy the CNC'd Champion irons.
If you're dead set on upgrading your intercooler, it sounds alot more sensible for you to look into an upgraded stock location, such as the CAS V4 or BGC stretch. I'm sure other vendors have versions of this too. There's about a $200 difference in the IC cost, and also,,, you don't have to do a bunch of cooling system upgrades to support that big FM, which are expensive too!
Just think about it, and get more input from others. I continue to say it; "bigger is not always better..."! Too many people go out and buy huge turbos, or huge FM intercoolers, etc, and then wonder why their car slowed down. It's all a matter of combining the right parts, in the right order, so as to maximize and compliment each piece and maybe even spend a little less money...
Again,,, what are your goals in the foreseeable future?
