You can mount the MC below the slave cylinder, for both brakes and clutch. Street rodders do it all the time with floor mount pedals and MC's mounted below the floor.
The trick is to use a residual valve. They prevent the slave cylinder from draining back to the MC. 2psi should work well for the disc brakes.
Not sure about the clutch, bit I'd start with 2psi there too. The Ford throw out bearing is designed to ride on the clutch fingers with a little bit of pressure. That's to reduce noise. If the bearing is noisy, try a 5 psi valve.

For bleeding, connect the reservoir to the hard line with a 6" braided soft line. Or just replace the hard line between the reservoir and the MC with soft line, about 6-8" longer than what you need. Unbolt the reservoir from the fire wall, and cable tie it to something higher up. That should make bleeding pretty easy. When done, coil up the soft line, and bolt the reservoir back in place.
Be sure and use a soft line made for brake systems - other lines get eaten by the brake fluid.
