It 'might' work but I wouldn't do it for longer term reliability.
You should be able to use 74HCT93...? I found this:
"LS means Low-power Schottky, one of the many types of TTL (74xx series) logic. This was the less power-hungry but slower descendant of Schottky.
'LS is all but obsolete now, it has been replaced by HCT, a CMOS-based family that is compatible."
