regenerator/displacer piston question

I'm just getting into how it all works.

Can someone please say, can the displacement piston be made out of a
porous material needed so that it double duties as a regenerator such
that the gas goes through it and it absorbs some of the heat and then
gives it back when the gas goes the other way? If not why not?

I mean can I pack a hollow cylinder with the regen material dense
enough that it provides the same gas flow as goes through the
regenerator?

thanks, George

I see maybe I put this in the wrong forum. It is for my education but maybe I'm supposed to use the Power Producing forum. Sorry about that.

Dear George, I see that this question is ages old, and by now, you would know the answer. But this is the first time I see this site. I think the answer is yes. If you arrange things right, you can replace the displacement piston with a regenerator.
