If said DPS jobs had damage avoidance/mitigation abilities such as Evasion/Parry at rank A- or two levels of Utsusemi then sure. Struggling to think of any aside from Dancer though right now, which I also used as a tank, maybe you could help out.

Enmity generating ability : Boost (Check)
Mitigation skills : B+ Evasion, A- Guard, Utsusemi from /NIN (Check)

I wonder why we haven't seen that more
