This is will only make all the people that know you not able to contact you (well, you might consider that a feature, but let's say this isn't what you're going for). First you'll have to contact each of them and go through the whole "who are you?" dance, that is if you don't fall into one of the many options that makes them ignore unknown numbers in the first place, and even if they see your chat or call don't take one of the other deny/ignore/report whatever option, especially after the scary "be careful with unknown numbers like this" message. And then after you iron out who you are with each and every person you might want to chat in the future with 90% won't even save your "alternate" to their address book, and from the remaining 10% if they don't contact you often enough to be at the top it'll be 50/50 chance next time when they try to do something to be on the right number (as it's not a special address book, but the one that's shared for everything, including regular calls and SMS).
Wouldn't it be easier in the first place to not post your status like "I'm off to Maldives with my secretary, losers" and a similar profile picture (switched to "visible to everyone") if you don't want that info to be public?
Also what has anything to do with the tablets? You can have a second (and a third, and a fourth) "linked" device beside the main one. These can be other phones, tablets, desktop apps, or logged in browsers. That changes nothing, it's the same account, with the same things visible (or not), etc. If you meant to take even ONE MORE number for the tablet that's bad, for the reasons above.
