A panoramio pic shows that the up platform ends at the overbridge anyway,

be reduced headroom for passengers under the bridge if the platforms were
extended, as well as passengers having to move track side of the safety
line to pass under the bridge. Presumably extending the platforms in the
up direction would entail placing the arch span of the overbridge that
crosses the line with concrete or steel beams supporting the roadway,
which would I guess entail a significant possession of both the line and
roadway.

They seemed to manage just fine with the Boleyn Road bridge when
extending Dalston Kingsland's platforms not so long ago.

Thanks for the comments and information. The road bridge crossing over
Feltham station platforms is not very high or wide, so using that end
would probably need a new bridge.(Expensive) There have been rumours
for some time that the level crossing might close to road traffic
(cheap) so that could be the solution that is eventually adopted. Time
will tell.
