You could run into issues down the road depending upon when the change of status is approved for your request for F-1 status. USCIS applies the last action rule. This means that if your F-1 change of status is approved after your status has changed to H-1B, you will no longer hold H-1B status. I encourage you to discuss the matter with your employer's attorney.
