I just read on Wiktionary that the Late/Vulgar verb mensuro (I measure) comes from Classical mensura (a measure or measurement), which comes from mensus, the perfect participle of the deponent verb metior (I measure). This provides a way to express the meaning of metior in a passive sense: mensurari (to be measured).
Are there other non-deponent verbs formed from perfect participles of deponent verbs like this? Is it a normal, reasonable way to make a verb? If so, it might provide a secondary answer to this question, about how to give a passive meaning to a deponent verb.
I tried deriving such a verb: sequor > secutus > secuturo, but a quick search turns that up only as the dative/ablative of the future participle secuturus, and no secuturare (which does sound very clumsy to my ear).
