HOV decal - bumper replacement - Q

Friends: I need to get my bumper replaced as someone rear ended (very minor but needs to get the bumper replaced). If so, I may lose my green HOD decal. My current decal was issued(for the first time) in April 2017, valid till the end of this year. If I apply for a replacement decal, I may get the RED decal, which gets expired by the end of this year. Do I have another option to apply for the brand new, 2019 issued(4 years valid) new decal? What is your advice? Shall I nicely remove my current decal(with some heat gun etc) and re-stick it on the new bumper(I dont think this re-sticking would hold like the original glue). OR shall I go ahead and apply for new decal now(I will have the insurance pay that cost) and apply AGAIN at the end of this year?
Pl advice. Thanks

 

Answering my own question: I was able to delay my bumper fix and now I got an invitation to apply for new 4 years valid decal from DMV, jumped on it.

 

Update: I got my new HOV stickers (RED) valid till the end of 2021. Going to put them on my car tomorrow.
