Timu+Inparusu=?

[Timpulse]

so i was wondering if someone could help me i have recently started learning Japanese and i was curious how to combine words for nicknames like i know
Tim is ティム = Timu
& Impulse is インパルス Inparusu

so how would i go about knowing how to fuse the 2 in Romanji & Kana?

(truth be told i am looking to make a Kana Header with this exact fused word to use for a future blog when i do visit japan)
