My only concern with pushing Pan F would be the increase in contrast. As really you are under exposing and over developing. Pam F is a slow film and doubling the speed you are going to get an EI of between 64 and 100.
Personally I think you would be better served with using a 100 or 400 speed film and processing normally.
I agree with Mike. I have enough problems fighting to get decent shadow detail with Pan F at 50. With some developers I even have to under-rate it. It would probably be better to use a faster film and save the Pan F for what it does best.
I also agree with Mike and Neal. Unless it was an emergency and you had to push PanF, why do so purposely? FP4+, Plus X, HP5+ and Tri-X are better suited for higher ISO's.
On pp. 53-54 of the "Film Developing Cookbook," Anchell and Troop discuss using a slow film like Pan F+ at double the rated speed in the Beutler developer http://www.jackspcs.com/fdnb.htm. I have tried this combination (Pan F+ at ASA100 with the Beutler developer) and found that the resulting negatives print well with shadows that are present, but probably not as "luminous" (pushed out of the toe region on to the straight line of the film curve) as some are wanting.
So whether Pan F+ "pushes well" depends upon what results you want. But I have gotten printable, satisfying results at ASA100 with the above combination.
Good luck!

Does PanF+ push well at all?
I've got Ilfosol S and whatever Freestyles "Arista" developer is, and could stop and get some Rodinal if need be.
