pickup questions

[MrSister]

basssically this is the first time ive ever thought about putting another pickup in my bass
i have a daisy rock bass with two active emgs

i was thinking of getting a DiMarzio Will Power Neck - DP145 pickup as i feel the bass doesnt sounds powerful enough as it is

ive got a few questions about this

would i be able to get the dimarzio pickup fitted as a neck pickup (alot like billy sheehans bass) as well as keepin my emgs?

or would i have to get my emgs removed to have the dimarzio fitted?

i hope someone can help

thanks
