I don't think so. Synth calls kernel system calls directly, using
assembly language. I expect this part needs re-writing into 64 bit
code.
Also, eCos is very much used on 32 bit systems. I don't know of
anybody using it on 64 bit systems. You are bound to run into problems
with assumptions that sizeof(int)==4 etc. However synth probably is a
good platform to find and fix some of these, once you have done the
basic HAL port.
