Option vs 6-2

Most of the teams in our MS conference run a 6-2 defense. To keep things simple for our 8th graders when they get to HS, I try and run the majority of the same spread offense our HS runs. This is what I was thinking for a simple QB-FB give/keep option play. I am going to have the PST go out and attack the DE. The Qb will read the DT for the give-keep key. If he keeps it, he will have the DE blocked by the OT.

Any thoughts or concerns as I have this "drawn" up?
