Hot water tank, superstore vs direct heated

I currently have two 80 gal superstore tanks that were installed in 2005, 7 unit condo building. I am guessing they are coming up on the end of their service life and would like to consider my options. Would it make sense to replace like to like or is there a newer option that would let me heat off the boiler during the the heating season and use a heat pump during the warmer months? Would this be more efficient?

    I mean they are stainless steel, unless you have particularly bad water they probably have quite a while left.

    The only way I know of that you could do a combo with a boiler as the source part of the year and heat pump in summer would be to use a heat exchanger and circulator to heat the tank from the boiler and i'm not sure if there would be control issues with the heat pump control with that. and you would lose your stainless tanks because as far as i know heat pump water heaters are all glass lines steel tanks
