68060 on a 68040 Accelerator card?

[wildstar1063]

If the pinouts for the 040 and 060 chips are the
 same, and the only difference is the core voltage
 (3.3 vs 5.0) has anybody ever successfully modified
 a 68040 accelerator card to accept a 68060?

It looks like all you'd have to do is change a Voltage
 regulator and the clock crystal.

Ok someone with more experience shoot me down now

Are ther any web pages of people who have tried the
 Sonnet QuadDoubler mod?

I'd like to see what problems they encountered

This guy has been selling them on eBay for 14 dollars
 He does not have any up right now, but here is the link
 to the one I bought.

Has any one seen this thing?

It is an adapter socket to use a 060 in an 040 socket, looking
 at the circuit in the middlle, it looks like it has it's own voltage
 regulator built in.

It's really expensive though
