As you've heavily edited your 763 to fit the 764, why not go the extra mile and implement the

- 767-style overhead
- yoke
- 767 model of the fcu unit
- window and structure around the 77 elements
- circuit breaker panel.

i mean, you own the IP, and i think it would be a great start if you have 767 assets already working in the sim. because you know.. after not finishing the 777 series with the -300 non er and -200PW/RR, the 767 is the only next step the consumer base would want.
