Subscription based consumable in-app purchases

Hello,

My marketing team just notified me that they would like to update our in-app purchases. I'm worried that we might run into issues during the review process so I wanted to get feedback.

Currently, we have monthly and yearly recurring subscriptions. This gives the user access to create unlimited number of projects in our app. The change we want to make is to limit the number of projects allowed in a single month, but still have the purchase a subscription. For example the tiers would be:

Tier 1 - Free - 1 project per month
Tier 2 - $10/month - 5 projects allowed per month
Tier 3 - $20/month - 10 projects allowed per month
Tier 4 - $30/month - Unlimited projects allowed per month

We will keep track of the number of projects created per user on the backend and will allow or block access accordingly. If a user runs out of projects for the month, they will need to subscribe to a higher tier subscription.

Any feedback regarding whether or not Apple will allow a consumable/subscription purchase model like this?
