Hello,
I guess this should work though i have not done this personally before.
Few things I would suggest.
1. Check who is the vpc operation secondary(sh vpc)
2. Shut the ports between that and the 4948 and remove from bundle.
3. Configure it as L3 and establish neighborship.
4. Once it is done, move to the other port.
However i highly recommend to do this in MW to avoid unforeseen issues.
Hope this helps
Madhu.
