Offering an opinion, the easy answer is yes. The difficult answer to give, is doing what, or for whom?
I'm guessing that most of your experience is likely in GA types - that may well work to your advantage. Medium sized GA manufacturers (I'm thinking of people like B-N, Diamond, Adams, P&M, Cirrus...) tend to have quite multi-tasking workforces, and the flexibility to adapt jobs to people. Alternatively, you might find potential (albeit with a probably slow and painful start) to develop a consultancy activity serving several.
I'd suggest going and talking to companies like that - probably directly if you can (finding the "in" may be difficult, but worth the effort), and seeing if perhaps you can fit one or more roles that they could have. This is likely to be the only way ahead, since you almost certainly don't fit any standard job description that anybody's thinking of at the moment.
My feeling is that you are less likely to attract the interest of a bigger company (Airbus, BAE, Dornier...) since they tend to compartmentalise roles a bit more, and lack the flexibility to really use that sort of broad skills set. But, I could be wrong.
