If Sonny could hold frame for such a mission (and that's a big if at best), he could potentially bring some useful information back. He's certainly a better choice than Luca Brasi for that mission; Vito's cat would've been a better choice than Luca Brasi.
Then again, cats have a well-earned reputation as skilled and subtle infiltrators, con artists, and saboteurs. Vito could have gotten all the intel on Sollozzo he would ever need - for the price of just a can of sardines.
