My suggestion, which I've done in the past, is to frame a standard door
in front of the panel area and use a pre-hung flush door in front of the
panel. This is entirely to code, since with the door open there is full
access to the entire panel and then some.

The required working space width is 30" (NEC 110.26(A)(2)). So that
will fly if with the door open you have a full 30" from the face of
the door to the latch side stop.
