That shouldn't be a problem. Assuming your layers are called layer1 and 
layer2, an you want to intersect layer1's feature #12 with layer2's 
feature #23, you could do the following:

g1 = layer1.features[12].geometry;
g2 = layer2.features[23].geometry;
var intersects = g1.intersects(g2);

Andreas.
