Hey.

This is what I did.

I switched some parts due to some dude "me" did the drawing of the schematic quick and standing on his head.

Schematic

Is it gonna work or is it a big no-no?

Pretend R2 and C2 are a single reactance. Call it Z2. Now, Z2 is in series with C1. Call C1's reactance Z1. The impedance of that branch is thus (Z1 + Z2) in parallel with R1. In reverse, the impedance is (Z2 + Z1) in parallel with R1. So, does the order matter?

Exactly what I told him. =)

Yes, it will work. Series impedances are commutative. (a+b=b+a)

edit: this is a useful trick for finessing circuit board layouts
