A FIV+ cat is several times more likely to get FELV than a negative cat, they have about the same chances as kittens in catching FELV (or any cat with a weak or undeveloped immune system).
That being said, you have to go by quality of life. Even IF he does get FELV from mixing with your crew, would that be a worse fate then being left out on the streets, or where-ever he came from to begin with? There's very little risk to you FELV cats, if that was more of the question. FIV is ONLY spread through deep penetrating bite wounds. So long as you aren't getting any cat fights there, then your FELV cats wont be in any danger of getting the FIV from him.
