A bigger frame, quite likely.
A custom-built wheel, possibly, to get a 26" wheel whose hub width matches your dropout spacing.
If you can get the wheel to fit, you may need some way to adapt brake reach.

700c rims have a bead seat diameter of 622 mm, which is the same as 29" mountain bike wheels.
For sake of comparison, 26" mountain bike rims have a 559 mm BSD. 24" BMX rims are 507 mm in diameter.
