Can a Musaafir read his Asr in Zuhr time?

Q: Due to travelling by bus for lengthy hours, can a Hanafi read his Asr after Zohr in the time of Zohr if he knows for certain that the bus stops occasionally for 2 mins only (which is insufficient time to perform salaah) & the next lengthy stop will be after maghrib. There is no place to stand & read salaah on the bus, there is place to sit. If Yes, he can perform the Asr early, then can he make jamaat in Zohr time with other passengers who are in the same position as him? & now, suppose the bus suddenly stops for 10 mins during Asr time (which is sufficient to read Farz of Asr), does the Asr performed earlier on during Zohr time become null & void?
