Yes, it is totally fine.
Besides, reputation from edits are capped at 1000. So after your 500th edit suggestions, you will stop getting reputation.
Also you do not get reputation from edits, but from "approved edit suggestions". Knowing this, when you reach 2k rep, you will no longer be able to suggest edits on posts, instead you will be able to edit them without waiting for someone to review them. This will stop you from receiving the 2 rep per edit suggestion.
However you would still be able to receive 2 rep from edit suggestion on tag wikis until 20k.
