Yep, any stone that you use (aside from the 0% steady, lucky, astral, immortal), whether 5% or 35%, will have a chance in assimilating any other stat, whether its blue or white.
In a situation you are in now, most people tend to only use 10% stones cause it makes them feel better with the lower assimilation chance. Truth being, its really all the same chance. Ive had a 5% str stone assimilate my crit on an old 68 bow from +90% - +0%
