I thing it is not goof idea to combine peptides from different genes. In
the case I would suggest to apply TFastx/TFasty (i.e
.http://www2.ebi.ac.uk/fasta3/newfasta3.html).
As far I remember there is no mimimal lenth for query in FASTA. It seems be
more sensitive than BLAST against DNA (particularly EST) database because a
frame shift is allowed.
