Question: combining 2d and 3d animations

I have one 2d and one 3d animation that I want to play at the same time.

p1:=animate(sphereplot, [exp(6*sin(t))-1, theta=0..2*Pi, phi=0..Pi], t=0..3, frames=100):
p2:=animatecurve(rhs(sDE), t=0..3, frames=100):
display({p1, p2});
Error, (in plots:-display) cannot display 2-D and 3-D plots together

I also tried using:

p2:=animate(implicitplot,[(i)^2 + (j)^2= (rhs(EQ2))^2,
                               i = -exp(6)..exp(6),
                               j = -exp(6)..exp(6) ],
                 t=0..3, frames=100);

that lets display({p1, p2}); work, but it puts them on the same axes. I just want to be able to play the 2 animations together, one above the other, without putting them on the same axes. How can I do that?
