Only if it's not too much bother. it will be a long time before I will need them, but conversion to 5E of old adventures I hope to run myself is always of interest.
Okay here are the basics. This is based on my home brew monster creation system based on monster level. I use it to covert materials from previous edition. The proficiency bonus for each monster is based in the level/HD and not the CR. This is the way I do 4e (4e is more a direct conversion than previous editions).
1) Start with the 4e stat block.
2) HP = 4e hp minus 20 for standard, minus 40 for elite, and minus 80 for solos. Inions have 5 hp.
3) Attack bonuses are cut in half.
4) For attacks against Fort, Will, and Reflex, they are converted to saves will DCs equal to 8 plus half the 4e attack bonus.
5) AC is 11 plus proficiency bonus (plus two for soldiers and minus 2 for brutes).
6) For damage, it is the damage in the stat block plus level (plus half level for minions).
7) Ability checks and saves for the monsters are done as a multiple of the proficiency bonus. I assign a level of proficency for each check (as they come up) as follows.
-1 = something you are bad at
0 = not particularly good or bad at it
1= good at it
2 = really good at it
3 = awesome at it (something you may have Skill Expertise in) — used rarely
Then the check bonus is that number times the proficiency bonus. For example, a level 6 ogre would be really good at strength checks so it would have a +6 to the check (skill level of 2 times the proficiency bonus of +3).
Those are the basics.
