Is there any way to take an F100 or F110 and superdupercharge it rather than using what appears to be 2 F414 type engines?
Yes, the PW F119 or the GE YF120 engine. The F110-132 is used on the F-16 Block 60 aircraft but I don't think they upgraded the intakes from the baseline 'big mouth' Block 40/50 jets.
The F119 engine is very expensive, if it was available for export at all. The F414 EDE is available, relatively cheap (A prroduction F414 engine is around $4m each) and high performance. The KAI F/A-50 is slated to use a single F414 engine. The F/A-18E/F Super Hornet uses the F414 engine in the fleet, and the F/A-18 for Brazil would likely get the F414-EDE engine.
For instance, a F135 engine wont be fitted to a F-22 upgrade, as it is not optimized for supersonic flight. It uses a larger fan for increased thrust. The F-22 engine bay wont accommodate a significantly larger fan either.
