I gave it a try but with an BC557 transistor and 4K7 resistor.
Testing with blit read, blit write, checking colours with pixel, reading from and writing to SD card all seems to work.

Edit:
After further testing the bc557 with 4k7 resistor doesn't work.
The colour code is read back incorrectly, every lsb is read back as 0.
example:
Clearing the screen with rgb(blue) and reading the colour code back with pixel returns 254 instead of 255 etcetera.

oh well..
