Synonyms of 'feasible'

Every now and then I get a sinking feeling that my vocabulary (along with many other useful mental processes) is slowly deteriorating. So occasionally from now on I might post random synonyms and words of the day from a dip into my thesaurus and/or dictionary.

Today's random synonym is : feasible.

feasible = practicable, possible, reasonable, viable, workable, achievable, attainable, likely ≠ impracticable 

'Feasible' in itself is not a very common or overly used word. Most people usually nowadays say 'doable', which I think is quite a new trendy oversimplified version of 'possible'.

EG. "Shall we meet on Thursday at 2pm? Is that doable?"
