Nope it won't drive PicStart directly. But now i see what you want to do....

With the latest MPLAB version, there's no more ways to launch PICStart from MCS. So what you need to do, is to compile in MCS, then in MPLAB, enable PICSTART, Choose your PIC device, then IMPORT the compiled .HEX file. Once done you just program your PIC.

It's sounds long to do but it works here.

OR you may try PICp...

In theory it's suppose to work, but i've never tried it myself.

Don't give up, you're close!
