This is not a direct response to your query, but a suggestion anyway; you
could bring down the number of pins required for the connector, and perhaps
save 2 pins on the CPU as well.

The pins for programming (clock and data) dont have to be dedicated for the
purpose; during actual operation of the PIC, they could perfectly well be
serving some other purpose.

For example, I have designed a pump controller with a serial output to be
connected to the PC; I am using RB6 and RB7 (bit banged) to achieve this.
Therefore, the same connector can be used to do ICSP as well.
