Assuming that the auto router you're using is even capable of laying this out sensibly, you haven't configured it to do the right thing, so let's just forget about that - it'll take less time to do the manual layout. In fact, it should take less time than it'll take you to read this answer, assuming that the components were placed is good locations (they likely aren't!).
What you show isn't a switched-mode regulator, it's just a switched low-side power stage. The layout should be done manually, using large copper fills, to minimize the current loop areas. Since you're designing a component for use in a larger circuit, minimizing the pulsed current loop areas in the system is just as important as in the subassembly you're focused on. It seems to me that your idea is to have flying wires going to J2, J3, J4 and J5. Those wires will act as parasitic inductances and can potentially destroy the components due to inductive kickback. J1 may also be critical since gate drivers usually slew fast, so the kickback on that wire may well break down the gate insulation.
To review your design, we need to see the entirety of the switching regulator circuit, so that the best partitioning of the circuit can be suggested. It is highly likely that the subassembly you're proposing should not, in fact, be a sub-assembly, but rather a part of the larger regulator circuit - or at least the pulsed high current loops need to be on the same board, i.e. the input capacitors, the switches, the inductors, and the load capacitors, all need to be close-by, and the loop area minimization needs to be an integral aspect of the overall design.
TL;DR: Tell us what you're actually designing, since what you show is just a little component of something bigger, and as shown it's unlikely to perform satisfactorily or even at all.
