Why do you want P-channel devices to make an H-bridge, for a "switcher"? There must be areason why all the commercial H-bridges out there all N-channel.

Default Reason for N-channel

I think the reason is that the on resistance (often) is lower for N-Channel types than for P's.

For a bridge I think you really only need on type.
