I am person left out of the happy CUP-party, at least for now - my rig is too old, and a new one won't materialise as soon as I hoped. So for the moment I can only drool and dream. And use HSFX 7 to gain access to the wonderful world of modded 4.12.
As an avid campaign builder and FMB user I have of course noted the CUP campaigns isn't coming as fast and thick as one would wish. And I of course know from my own experience that converting a 4.10 campaign to 4.12 standards take time, at least if you want to do a REAL upgrade, with taxi-to-take off, formations, new objects, vehicles and aircraft etc. (Bergkamp has said in another thread that it took him three weeks to convert a single campaign, and it can mean a lot of work for sure.)
One way to get more campaigns to CUP without too much hassle would be to make CUP HSFX-compatible.
Because, if I understand this correctly from people that have converted my HSFX 4.12-campaigns (like "Fighter Boys"), the things that mis-match are a couple of missing objects and vehicles. With CUP obviously having it ALL there is in the modded Il-2 universe this surprises me a bit.
With all the CUP updating and polishing going on, wouldn't it be easy to add those things that can't be found in HSFX? The result would be a sudden influx of campaigns to the CUP family!

Or am I missing something here, making such an operation impossible?
