Yes, it would - the spell would now allow the use of Distant Spell metamagic!In fact, if they reprinted the PHB and changed the range entry of spirit guardians to 'range: 15 feet', nothing would change about how the spell works!
Personally, my argument for disallowing Distant Spell for areas of effect is the low point cost for exponential increase in targets.
On a grid, a 15ft radius casting affects up to 36 medium creatures. A 30ft radius casting affects 120 creatures.
That is way too much of an increase for 1 sorcery point.
