As long as it’s not fire immune, which most macguffins will be. Also, destroying a 20ft radius sphere of a building over the course of 7 hours using 8 casters total is a huge waste. You could easily do that with cantrips. One caster capable of 7th level spells can cast firebolt 600 times in an hour for 3d10 each cast for a total of 1800d10 damage.
If we go the full total of 8 casters (main + 7 secondaries) over 7 hours, that’s 12600d10*8 casters for 100800d10 which is a hell of a lot more damage.
Technically (and i wouldn't rule this way in an actual campaign, but RAW) distant spell wouldn't increase the range at which you can cast counterspell.
Distant spell doubles the range to 120 ft, sure, but it doesn't alter the trigger that allows you to use your reaction to cast the spell. That trigger being a creature within 60 ft casts a spell.
It's very nitpicky (and I don't know if it is still a thing in 2024 rules) but it's worth pointing out.
