For all that matter, I'm using one of the Adafruit boards in my CB-to-10 conversion. It works well. Only using one clock tho, but your si5351 routines.

We could mount an si5351 the Adafruit si5351 breakout board to the back
of the uBitx:

I'm thinking some duct tape on the back for insulation,
then solder wires from breakout grounds to uBitx groundplane securing it
Steal the old clk0,1,2 lines going into the uBtix for use as i2c SDA,
SCL lines.

Nik is successfully using that Adafruit board on his Raduino replacement:
And we were initially using the Etherkit si5351 library on the Bitx40.
All good choices.

Another solution would be to separate the Si5351 from the raduino.
Put it on its own board that plugs into the uB. Pins 10-16 pass thru
to another connector. Another connector connects the I2C to the
raduino. Then you can put the UNO part of the raduino (or use
something else entirely) wherever you want where the Xtal won't be
an issue. That also gives more options for boxes and mounting.

I have it partially finished in KiCAD but other things have gotten
in the way so it's on hold. I tried to get Mike Hagen to do it but
he didn't seem interested.
