I modified the circuit as much as I can. Can I modify it any further?

That modification is incorrect...
Starting from the right
2\Omega + 1\Omega=3\Omega (Series Resistance)
{(\frac{1}{6}\Omega+\frac{1}{3}\Omega)}^{-1}=2\Omega (Parallel Resistance) 
2\Omega+2\Omega=4\Omega(Series Resistance)
{(\frac{1}{4}\Omega+\frac{1}{3}\Omega)}^{-1}=\frac{12}{7}\Omega(Parallel Resistance)
\frac{12}{7}\Omega+4\Omega+4\Omega=\frac{68}{7}\Omega=9\frac{5}{7}\Omega \approx 9.7\Omega(Series Resistance)
Finaly the Circuit will be left with only one resistor of 9.7\Omega and a cell of 120V
