This is the same thing I was thinking, and was about to suggest.

Just tie in another I/O line (setup as a high impedance input, which is the
default on most PICs) directly to MCLR and set it as a low output when you want
to physically reset the uP.  The only other hardware you "might" need is a
resistor between that I/O pin and MCLR, but I don't think that'd be necessary.
