A system I have been toying with over in House Rules is to give out a LA when multiclassing without increasing HD. HD is based on your highest level class and classes beyond that simply add to LA. In its current incarnation you gain a +1 LA for each class beyond the first, plus an additional +1 for every two levels beyond 1st in any additional classes. So a Ftr1/Wiz1 has an ECL of 2, but only 1 HD, a Ftr3/Wiz3 has an ECL of 5 but only 3 HD, a Ftr5/Wiz5 has an ECL of 8, but only 5 HD, and so on.
It is similar to the AD&D multiclassing rules and similar to gestalt, but in theory it sounds good. It is not as good as AD&D multiclassing (you won't remain as close in level to your party members), but it is not as bad as 3e multiclassing (a fighter/wizard has a higher bab than a wizard but lower than a fighter and is intermediate in class abilities between half and full, which in terms of effectiveness more closely approximates half).
