I still have a 170mm crank arm from Chiddu, which I plan to put in my MTB which came with 175mm crank arm.

Phew. I spent 1 day, dismantling, cleaning and washing. Spent another half a way reassembling. Spent hours trying to find the right parts online :-D

I will never to this stupid exercise LOL.

I forgot to mention that I also have a front wheel with a dip in the rim. I plan to rebuild this to correct the dip as I did earlier. I don't have to change the hub here at least as the cups are still good.

Amazing. 

May i suggest a bull horn handle bar and bar end brake levers?

How is the quality of chain tensioner and single speed converter kit?

[Opendro]

Chain tensioner is of very high quality. Single speed converter looks like an aluminum and feeble. I would have preferred an steel or alloy.

Chain tensioner cannot be adjusted for alignment. Since I placed the crank in the mid ring position (instead of the small ring or single crank position) of a tripple crank arm, I had to keep the rear cog considerably outward. This didn't go down well with the tensioner. I inserted a few washers to keep the tensioners aligned. Fortunately, the nut for the tensioner to the derailleur hanger is of sufficient length to play around with a good range of washers.

I won't spend on the handle bar and brake levers again :) Thanks for the suggestion though.

I have decided to buy a stand as well since I'm using it for commutes.

What an expensive way to what some would call downgrade a bike :). But since you've already done this, you might as well sell off the shifters and buy a pair of bar end levers and bullhorn bar. You'd actually be making money out of this whole affair than spending. If you are averse to spending more money, you are better off buying reach adjustable chinese cross levers for as less as $3-$4 each and a bullhorn bar would set you back by around $15-20 max. You should be able to recoup much larger amount by selling the drop bar and STIs currently on the bike.
