Is it possible to make a Sonnet HARMONi G4 500/FireWire?

So I'm thinking of getting a iMac G3 Tray Loader and upgrading it to have a Sonnet HARMONi G3 upgrade, but also have a G4 and Firewire 400. Well, the 600mhz uses the G3 750cx, which I didn't think can be upgraded, but the 500mhx has the regular G3 750 and the 750 can be replaced with the G4 7410 cpu. In fact, all tray loaders and pre-2001 slot loaders have the 750 and it can be replaced by a G4 7410 with speeds up to 500mhz. Since the 500mhz version of the Sonnet Harmoni card has it, I wonder if it's possible to replace it's cpu with a G4 and have it work?

Imagine installing the Sonnet Harmoni 500mhz and the drivers, than upgrading it to a G4 to have a G4 sonnet iMac G3 tray loader and Firewire 400, that would be cool.

Sounds cool, however by the time you've spent hundreds on this you might as well go get a slot loader and get a G4 CPU transplanted - or an eMac!

To the point everything all of us have said in previous threads:

This sounds like a fun project!

But, if you're not up for the project, an eMac is a great suggestion. You'll get a bigger, better (1280x960!) display, better speakers, a better optical drive, the G4/700 (at minimum), better graphics, a faster system bus, a third USB port, AirPort (compared to the trayload iMacs), and I believe the ram/CD/HDD are all easier to get to on the eMac as well.

But the eMac doesn't have the color variations as the iMac G3. Also, couldn't someone else do the project for me with $?

The RAM is easy to get to. The DVD & HDD can be gotten at, but it's annoyingly more involved than it seems like it should be.

That said, I have the most top-tier eMac model Apple ever produced, and I can confirm it's a very nice and capable machine of that era. About the only way I think Apple could have improved this machine would have been with a slot-loading DVD drive to mitigate the need for the big flap that opens on the front. Otherwise it has a solid 1.42 Ghz G4, a 167 Mhz FSB, and an onboard AGP Radeon 9600 GPU. At the moment it's my favorite machine to play Myth TFL/II on. :)

I know that Dosdude1 and Herd can do cpu swaps, so they have the tools to remove, reball, and resolder PowerPC cpu's.
