I wouldn't, an account like that is worth quite a bit/hard to skill up to, and the ban rate right now on both versions of RS is quite high, so it'd be silly to risky such a good account when the risk of a ban is so high.
Lost my 2.3k main the same way. Can't say I "regret" it entirely but at the same time I think about it and just kind of wonder why I allowed myself to continue botting even after a temporary warning ban......
However, a lot of those levels were botted to begin with. My ban was for botting on '07, but I botted for months straight (suicide aviansies and shit @ gwd for cash, 99 con, 111 dung, 99 combats @ pest control, plus a bunch of others) prior to the introduction of EOC/RS3/'07 and never got caught... I guess I got cocky....
