A very good call.
get it on the ground, then you've plenty of time to sort it out.
I remember diverting to AMs for a frozen wing anti ice valve. It thawed out on final approach, but the option to continue at low level, through an active front full of ice just wasn't a good idea. Everyone's inconvenienced, it costs money, but EVERYONE is alive and well and untraumatised (if a little stressed).
If it's that important to be there, then, then go alittle earlier and give yourself, and your operator a little slack to sort things out if need be.
