If I were you I'd try out the free MorphOS download on that PowerPC accelerated A1200 mentioned in your SIG first since most of what you said you wanted to run would require EUAE to function at all on the Peg2.
Remember that EUAE only has a JIT compiler for the Intel versions. The PowerPC versions use interpreted only. You'd have no better luck with MorphOS than AOS 4.0 at getting any decent performance but at least you wouldn't have to wait for new hardware.
-edit- Not sure if MorphOS supports the Mediator bus expander on the A1200.
