Psp nub idea/ question

[neverused]

I was wondering if it'd be possible to use a variation of sifuf's diagram or some other similar idea to use a psp replacement nub to replace a four way directional pad. I know of the razor and a2d projects, but I would like to be able to cut the circuit out with a switch(s) to switch back to an analog nub quickly rather than have it as a dedicated switch. Does anyone have any suggestions as whether this would be feasable? I would think so, but I have yet to try it.

Thanks,

Alright, can someone tell me if this would perhaps help?
