Copy the config off-box, trim it down to just the subinterfaces, copy
that resulting file to bootflash. Delete the members, add the new
members, and if you have to restore the subinterfaces, copy
bootflash:subints-config-bits running-config
It's not hard, you can have your ducks all ready to go, and drop it
right back in.

Well tried this last night, and the ASR1K did not cooperate.....4500X, played
nice and behaved like the 2960 (Adding 10G ports to the portchan, rejected them
due to speed difference, but still adds them to the portchan, but in suspended
mode....so all good there, but ASR1K, (As well as only allowing 4 member ints
in a portchan.,,which was a tad inconvenient), when attempting to add the 10G
port, it simply rejects them due to bandwidth, ie, does not put the port into
suspended mode/add it to the member Ints config......so, if you remove the 1G
links, portchan would have no members....you would have to add 10G members
after removing all 1G.....but Im almost positive the ASR will not allow me to
remove all the 1G ints, due to the subinterfaces (I didnt want to test this on
the production ASR1K, maintenance window was only short).....so, going to test
it on an asr1001, and see what the result is....I really really hope I can just
shutdown the portchan, remove all the 1G ints, add the 10G;s then re-enable the
portchan...I hope I dont have to remove portchan, remove 1G ints from it,
re-create it, then add the 10G's.....subints are referenced in ospf/bgp
etc....wouldnt surprise me if they were dynamically removed...other option is
to change startup conf, save, reboot (Or potentially save, then replace running
with startup.....but having done that on previous occasions, it doesnt always
go smoothly 😉)
