No. You could use a view with UNION ALL perhaps.
(The subtext here is that past discussion of inheritance has generally
focused on *eliminating* differences between parent and child tables, so
as to make query planning and execution faster/simpler. That is, when the
discussion doesn't consist of somebody wanting to get rid of inheritance
altogether. I think the enthusiasm for supporting even-less-compatible
child tables will be not distinguishable from zero.)
