Some inaccuracies in the Ward Carroll video from retired USN & US Army guys.
The C-130J line is not closed and any new or in-use C-130J could be turned into replacement HC-130J and/or MC-130J at a maintenance depot given a lot of time & $ but the USAF does have significant numbers of each so probably not necessary.
If indeed the recovered WSO is a full colonel (US O-6), it isn't the 48th FW Commander - that is an O-7 post. The 2 x aircrew rated O-6s in 48th FW are the Deputy Wing CC and the OG CC. It might be the rank colonel was used in the POTUS announcement but actually meant lt col (O-5) which could be the sqn CC or DO.
