This uses the premesis of what they are pretty much currently looking at revamped. Space and ground will draw from the same pool of skill points.
(I did post this in another of my posts. It gives it a more RPG style tree using the simplified feel they seemt o be going after)


With the trees, tree is space and tree 2 is ground.
All trees now goto level 3, with a max of 5 in each rank
>Rank 1 give current rank 1
>Rank 2 give current rank 3
>Rank 3 gives current rank 5
>Rank 4 gives current rank 7
>Rank 5 give current rank 9
level 1 skills cost their rank in Skill points (1, 2, 3 , 4, 5) ~~ 15 Skill points to max out
Level 2 cost their rank +1 in skill point (2, 3, 4, 5, 6) ~~ 20 skill points to max out
Level 3 cost their rank +2 in skill point (3, 4, 5, 6, 7) ~~ 25 skill points to max out
You gain 5 skill points with every level (255 max skill points)
There are 64 skills total, but only 46 available to each class.
You must unlock rank 3 of a skill tree to access the next skill in the tree (follow the yellow lines)
(Example: To unlock Attack Patterns, you must spend 6 point in Starship Command and 9 points in Starship maneuvers. that's 3 levels in game to unlock it.)
The Green Boxes are class specific.
What this also does is allow better charcter focus without being able to max everything.
Sorry to say, you can't escape respecs no matter what you do to the tree. Respecs are a natural thing in MMOs/RPGs. I still vote to make respecs free, or make respecs rewards, and not just for those who pay to play as it is.
I'd also suggest a major leap of faith to go along with this tree set, that has somewhat bothered me since the onset of this game. Unlock the kits to all classes. How many times have to seen Jean Luc Picard perform a science feat in one episode, an engineering feat in the next, and then a tactical feat in the following. As a captain, you'd have some basic knowledge of all the skill needs of the ship, but you wont get the actual buffs from the basic lines unless you are of that specific class. THis will also get mroe use of duty officers, especially for ground.

But if they really are looking at the current skill sets with an "apply to all" aspect, this re-arrangement uses the skill they have now in beta but make an actual tree of it and not all the needless use of spending points in area you wont use to tier up, instead you unlock as you train in similar skills.
Instead of spending X Skill Points to unleck the next full tier, you train to rank 3 of the first tier to reach the next set of skill in that tree.
With the blanket tiers they have now, i'm forced to spend in skills I don't really want just to activate the next tier.
