these days satellite receivers that content providers like ESPN give to operators like verizon or comcast include a MPEG4 to MPEG2 trancoder built in so there is no extra equipment that handles conversion that u speak of.

Is MPEG4 even necessary?. Program the least viewed HD channels to start up as an IPTV streaming channel. It would take a second to start, it wont be instantaneous, but THESE are the less popular channels afterall.
Mpeg-4 is how a large number of channels are already being delivered to Verizon. Switching for those would eliminate any signal degradation occurring because of the conversion, eliminate the cost of running equipment currently handling the conversion, and free up space for more programs. The negative is that currently only the Motorola 7xxx series and Cisco boxes handle them so Fios would need to start doing switch outs. Note some models of customer owned boxes such as TiVo's can handle it.
