PNP Transistor with low base current
Yes, you can replace the transistor with a "pre-biased transistor" which has the resistor built in or you can replace it with a P-channel MOSFET. The diode is flipped and you'll have to pull it low for reset. 

The pinouts, luckily, arecompatible, check the case, they are available in several similar packages, 
such as SOT-23 and SC-70.
