In as far as I am aware of: No (not at present).
But wouldn't it be an option to use Subtitle Workshop (see link in my first reply to you) in two ways:
(1) to convert subtitle to e.g. .srt (SubRip) format
and
(2) to set the minimum (and maximum) duration time as wanted by you
(See post of earlier link:
SubtitleWorkshop's "Timing operations" i.a. provide in a possibility to "Set duration limits (maximum duration and minimum duration"))
Now, though I've no personal experience with it, I think it may be worth a try!
