I see no problem with mixing your Aikido with a sprinkling of other techniques.
Most of the early teachers that I studied with from the 1950s were nearly all Judoka and this showed in their tight positive technique, Kenshiro Abbe Sensei 8th dan Judo and 1937 all Japan 5th dan Champion, Masahilo Nakazono 6th dan KodoKan Judo - Tadashi Abe - Kazuo Chiba.
I would suggest you do what is best for your needs.
Time will tell if a student wants to follow the path of Aikido or any other martial art.
