Not sure about homebrewing one, but Down East Microwave has transverters
for 222 MHz, as well as 902 MHz, 1.2 GHz and above.
Assembled, they cost about $395; the kits are $100 less.
You might check them out at:

This is something that I had in mind as a further use for the new 6/2m
all-mode transceiver that T-T has in the works. I have an older model
Icom 706 that has only 6/2 meters (only 10 watts on 2m) as well as a
Yaesu FT-847 that could be used, as well.
Not only is the 222-MHz band not authorized outside Region 2, but use can
be very regional here in the US. There are a *lot* of 222-MHz repeaters
here in SoCal. Some think of it as a refuge from 2m, since there is at
least one repeater on every coordinated frequency pair on 2m. Friends
who operate in the VHF/UHF contests find quite a bit of SSB activity on
222 MHZ, but 1.2 GHz seems to be gaining ground at a faster rate.
