Husband name

All of my family is hearing, but my husband is deaf in his left ear and I'm thinking toward the future as he becomes increasingly hard of hearing investing in asl as a second language.

For now, I've come up with a sign to "call his name" across the room. His name starts with a J and he likes to play videogames, so I've started signing a J blending to a half / one-handed sign for playing videogames (A with thumb up). I just wanted to check with those more fluent to make sure this sign isn't already taken or means something unintended.
