Work spaces in cities where department has presence but agency doesn't

Hi - I know things are super uncertain now with the OPM/GSA "takeovers" which throws federal properties and rented space up in the air (what will/won't GSA sell/terminate? Who knows.), plus RTO. This whole thing with RTO also threw up in the air our plans to move to Denver (wasn't the whole goal to get us feds OUT of DC??? Whatevs).

We ARE willing to go back to work in person in Denver, whereas it would be very difficult in DMV because of commute vs. child care facility hours + unaffordability of homes closer to DC. Our commute would be 3-4 hours RT. In Denver, we can afford homes within 30 min of federal complex. Does anyone have any sense of how departments with agencies based in DC and that don't have dedicated office space in other large cities will handle office space for agency staff who are remote and living in those cities.

Ok, that last sentence was convoluted. Hypothetical example:

X department + 1-2 of its agencies have office space in Denver.

1-2 of X department's other agencies don't, are only in DMV, and don't currently have agreements with X department that would allow their staff to work in X department/other agencies' office space in Denver.

These 1-2 other agencies have at about 100 staff working remotely in the Denver area who otherwise would have to move to DC or lose their jobs, leaving agencies with too many vacancies in mission-critical positions.

Would X department be likely to work with these 1-2 agencies to allow them to use Denver office space for those remote staff? Which departments might be more likely/less likely to do so? (Departments with presence in Denver include DOD, Interior, HHS, Commerce, Labor, DOJ, a few others I'm not 100% sure about).

(edited to add last two sentences)
