Suggestions on lessening taxes on a large civil settlement

I am somewhat close to receiving a large settlement in an employment retaliation/whistle blower civil case my attorney is pursuing with the defendant company. This is not a personal injury type of settlement, so I know that are no taxes on that type of settlement/judgement.

My attorney is working under a 40% contingency agreement. I understand that I will have to pay taxes on 100% of the total of the settlement not just the 60% portion I receive after my attorney gets his 40%. I realize that annuities spread over several years lessen the taxes significantly but in my particular situation I need a lump sum payment and not an annuities type of payment.

I have heard that it may be beneficial to have the company we are settling with send out 2 different 1099s next year, 1 to me and 1 two my attorney with my 1099 indicating just the 60% I would be getting and not the full 100% we settled on.

Is this possible and if so how/why would this be advantageous? Also, if you have any other suggestions or ideas to lessen the taxes on the settlement, I would greatly appreciate your assistance.
