No, right now everything is below the pool level, and I don't think it is feasible to change that---I would have to run many pipes a long way.
Actually shouldn't have to run anymore than you are now (2). The solar valve would just bridge the two pipes running up the house in a H configuration. The check valve would just be before the H on the supply side. Similar to below. The only difference is the pump and filter is lower than what is shown in the picture. But you only need a supply pipe and a return pipe to and from the house with the diverter valve. Also, they don't show the check valve but you should have that right before the diverter.
