Some attempts are going on with AP7 series. It is not the processor mode that 
poses a problem but the memory limitation. Memory footprint is the fat issue. 
Despite the fact that AP7 series has MMU and allows external 16-bit SRAM for 
additional memory, experience shows that virtualization still remains a fairly 
big challenge.

UC3 series have no MMU at all. Except for UC3A, no other series has extended 
memory support either. AFAIK, it is mostly a closed alley.
