PO Approvals - Budget approver field

Hi, we are using 9.2.

For each approval route that we have, we are exploring the idea of identifying a "route owner". who would have the responsibility of reviewing the routes regularly and submitting necessary updates to the appropriate person. Since we do not use Budget Approvers, it seems that we could use that field to enter an AB number for that route owner. Then we could report on that field.

Is it correct to think that as long as we do not have the Budgeting processing option turned on for any versions, that this is a option worth exploring? I don't see how it would cause any other issues.
