There have been several proposals offered, drawing on GE's development of the CF34 family since the TF34 was first bench tested 49 years ago, but funding never follows. The TF34-GE-101 (ex -100B) for example would insert tech from the CF34-8 (incl. FADEC), offering improvements in power, hot/high performance, responsiveness and durability.
The Air Force looked closely at a re-engining program in 2001 (15 or so years after the TF34-GE-100A Hot Section Life Improvement), but the study ended up unfunded. Boeing took another look in 2015, when it was considering re-marketing A-10s abroad, but again nothing came of it.
