Call own sign/verify callback - engine

I'd like that my callback is called when a sign/verify is being requested by
I've tried add a EVP_PKEY_METHOD to app_methods stack, that works good
however doesnt fit on my solution.
I noticed that creating an engine and set pkey methods there, it could solve
I looked at gost engine to have in mind what I should do.
So, in engine I call *ENGINE_set_pkey_meths()*, so far so good.
The issue occurs when I try to assign a RSA key. I call
*EVP_PKEY_assign(*outKey, NID_sha1WithRSAEncryption, key);*. The error
returned is *pkey_set_type:unsupported algorithm*.
Most probably I'm missing something.
If *EVP_PKEY_assign()*worked I will call *EVP_DigestSignInit(ctx, NULL,
sha1(), engine, pkey)*.
Thanks in advance.
