Trade Antonio Gibson for Keenan Allen (Half PPR)?

I’m in need of receivers (1 WR2, 3 WR3s) and have a glut at RB (2 RB1s, 1 to 2 RB2).

Half PPR, 12 team, 1 QB, 2RB, 3WR, 1 TE, 1 Flex (RB/WR/TE), 1 DEF, 5 BE.

Is the above a fair trade, or should I be asking for more than just Allen in exchange for Gibson?

I’m assuming this isn’t dynasty. In redraft, that’s a fair trade.
