I have to remark that as a RPG character-optimization fiend, I was determined to give my Steele all the perks relevant to an hypersexual killer machine lady, rules be damned, so I tried a save editing method very similar to the one Morrigan attempted, once the one Couch suggested proved inadequate, and I was entirely successful at it. At character creation and every level up, I made multiple save files, each one with one of the alternative perks I wanted, opened them in different online minerva windows, copied and pasted the relevant perk object in the perk array of the original save file, changed its name to a +1 array number, and saved the file. The system recognized and loaded the save file normally, short of the new perk being at the end of the list. Then I used a Sterilex and Fertite combo to make the system add and remove a new perk, and so rearrange the perk list in the correct order. To my experience all of the perks seemed to be recognized and work normally, with no errors or conflicts. Only a couple character-creation perks I used (Elasticity and Fertility IIRC) seemed to work by the system changing the relevant variables outside the perk array instead of directly applying their effects, so I checked the variables' values in the two saves and manully edited them in the original file. Dunno what was different for me.
I have been uncertain whether to try and remove certain bimbo perks I dislike by save editing, such as Ditz Speech - I fancy the 'nympho slut' and 'big-titted sexy body' parts of the bimbo fetish concept a lot, but dislike the 'brainless' part. Nothing can really stop you from turning your PC into a genius bimbo slut with enough Intelligence stat-grinding (or save editing), so Weak Mind is not much of a problem, but the effects of Ditz Speech are otherwise inevitable if you want the bimbo TF package, and grating when Steele should sound cool.
