Now, i've calculated the front to need 290.6mm spokes, so they'll be fine, but the back requires 292.6mm.

This on either side add's up to 5mm of a difference.

Will I be able to use 290mm spokes on the 36h wheel that requires 292.6mm? I'm using standard. 12mm nipples that protrude roughly 6.5mm out of the rim.

The spokes are threaded for around 10mm at the end of the spoke.

Hope this is enough info,
Cheers,
Paul
No.

If you've measured everything right, it's +/- 1mm tolerance. 290's will not work for a 292.6 (293). You will have little to zero tension on the rear, left side. Even if you tried to compensate by overtensioning the rear drive side. Do not do this.
