It depends on your GM. If he allows you to trade in requisition points from starting equipment for new weapons and wargear during regular requisition than yes, if not, you know the answer. Otherwise the whole requisition system would be out of balance.
But why go for Signature Wargear (Hero) which grants you up to 70 requisition points, when it would be better to choose the Signature Wargear/Signature Wargear (Master) Combination, which will give you only 40 points, but grants you +10 to all Attack tests? Or are you planning to get some additional upgrades such as a Deathwatch Suspensor (65 points total)?
Something along the lines of the latter, yes. If the base Req is not counted because of the HB's status as standard issue, I would Master-Craft it (20), then add a Suspensor (25), and a Motion-Predictor (20). (My character has to use a Heavy Bolter, his Heavy Bolter, for roleplaying reasons.)
I already have my first Signature Wargear, a standard issue Mk7 helmet (0) with integrated Auto-Sense Goggles (10), Geographic Mapping function (taken from a Cartograph) (5), and a Stummer (5). (I was able to treat them all as one piece of wargear by getting rid of the ability to share navigation information with my Killteam beyond verbal communication or drawing a map in the dirt, and that the Stummer is integrated to work with the helmet, so it actually cannot be used without the helmet on. It also helps that I slew a Greater Daemon of Tzeentch inside Watch Fortress Erioch while the GM was considering the gear build).
My next Signature Wargear (which I intend to upgrade to Master) will be a Chameleoline Cloak (which I would then Master-Craft). I'm a stealth-build Devastator (Gotta love the Honour Thy Wargear advances).
