1,000 gamer score challenge

So I was watching Brownman's stream the other day with him streaming for 24 hours trying to get 20,000 gamer score in that time frame (spoiler: he got it with hours to spare) and I thought "could I do that?".  Short answer: NO.  Long answer: No way in hell.  But it got me thinking.

Could I set myself a goal to get a set amount of gamer score in a set amount of time?  If so, what amount and how long to get it?  Would it be possible?  What would be a stretch but also doable for me knowing that I have a full time job and other responsibilities that might interfere with my plans?  So I thought of a slightly modified plan. 

What if I just tried to see how long it would take me to earn 1,000 gamer score?  Could I do it in a week?  Probably not.  A month?  Maybe.  How long would it take me?  Maybe if I knew that, I could devise a better, more specific challenge next time.

So starting today (because Lego Star Wars: The Force Awakes just came out) I'm going to see how long it takes me to earn 1,000 gamer score on Xbox Live.  I'm sure it will be a mix of Xbox 360 and Xbox One games.  Starting with Lego Star Wars.  Currently my gamer score is 34,517 as of this exact moment.  So that means I would need to get to 35,517 to finish this goal.

I know I can get a big chunk of that from Lego Star Wars: TFA but I'm sure I'll play other games.  Some new; some old.  How long do you think it will take me to get 1,000 gamer score.  Is there any games you'd like to see me play?  Ones I've started that maybe I need to finish?  Ones that I haven't started yet?  Let me know.  Maybe we can place bets.  What do you think my over/under would be?  Maybe you'd like to join me.  How long will it take for you to get 1,000 gamer score?  Let me know all of these things in the comments.
