Definitely a basement project.

A lot depends on weather this is a one off basement project or a commercial endeavor. If it's commercial, there are people who will sell you a packaged part that will do the 10 MHz to T1 conversion.

I have a board that does this, I could send you.

Couldn't you do the same thing much easier with the ICS525 chip ?
Neat and convenient:

Perhaps. The DS-1 signal has a pulse-mask which is not square. And
while the all 1s AMI signal looks like 772 kHz, presumably the D4 or
ESF frame would require some zero's in the 193d bit position. But your
suggestion leads to a possible 2 stage solution. There are CSU/DSUs
which accept
I would like to generate a DS-1 timing reference from 10 MHz, e.g a
T-bolt. Thought someone here might be able to suggest a starting point.
One approach is a PLL. You will have to divide 1.544 MHz by 193 and 10 MHz
by 1250. If you want to use the TAPR Clock-Block, I think you will need
