It is unlikely that any kind of bounty will make iMac G5 support happen any sooner.

Just my 2 cents ...

Not because it is never going to happen but at the moment it would be a waste of developer resources to spend more time on even more Apple PPC hardware options IMHO.

Currently, there would only be 2 MorphOS-Team developers who could add the support for iMac G5 IMHO. One is currently fixing the open G5 issues that have shown up with the MorphOS 3.2 release - and I'm not sure if he is keen on adding more to this list by supporting even more models - and the other one sees no point in expanding support to even more Apple PPC hardware options than there are now already ....

So whatever plan you come up with in this thread regarding iMac G5, it is unlikely to work out ...
