It's possible to get a Commlink up to a fairly high Sleaze. So if you're running silent you can probably come out a couple points ahead by slaving your Persona to a tricked out Commlink.
Commlink, Sleaze Dongle, MOS running Smoke&Mirrors, Stealth, and Signal Filter, Mod for more Noise Reduction, you've got 7 Sleaze and 1 net point of Noise. Combine with Trust the Data not the Lore Positive Quality and you could conceivably drop Intuition to 3 if you're using CFs and Sprites to handle the Hacking.
Probably not the most optimal set up, but for a Cyberadept who has more Nuyen than stats, certainly an option.
Willpower 6 Technomancer that is looking to Increase Firewall probably not so much, but you could get to an 9 or so Firewall if you tried. Fairlight Caliban Mod to increase Firewall, MOS running Encryption. +3 Firewall isn't nothing. May or may not be worth the Karma/Nuyen/continuous stun damage. And odds are a Commlink modded for Firewall isn't going to be able to get a decent Sleaze so it'll get spotted much easier. May or may not be an issue.
If only there was some way to have some kind of Device with a good Firewall and a good Sleaze to be a Master in a PAN...
