Looking for column recommendations/feedback

[EDITED FOR CLARIFICATION]

My goal is to build one head that can be used to create neutrals and be "detuned" to keep some flavor and be able to do one and done runs for whiskeys

My plan is this:
- 2" x 42"-48" boro column packed with marbles (thinking 6mm glass marbles due to relatively low available power)
- 12" coil RC above the "T" with a boro sleeve so I can see the condenser in action. I haven't decided if I want to go with a traditional double wound coil or go with a single wound with cold finger for centering of the returning distillate.
- 24" long x 2" graham condenser with a 1/2" inner coil again with boro sleeve

I'm going for a mad scientist look/feel that will still hopefully perform just as well as one made from copper or SS. I want to be able to see everything going on because it fascinates the hell out of me.

Am I correct in my thinking that I can remove some of the packing to allow more flavor to be carried through? Also, I was thinking about going with 6mm marbles because it seems that smaller columns with lower power seem to like the smaller packing. This comes from my assumptions after reading some of the threads discussing the use of lava rock and the outcomes of changing packing size. Additionally, if I'm using marbles, should I put them through a tumbler with some grit to give them a frosted surface or leave them smooth?

I only have about 1,450w at full power to work with at the moment to drive the still and the cooling water will be coming from a well pump with a pressure tank for stable pressure.

If this plan isn't ideal for my available power, what configuration would you recommend? This will be a slow process as money is tight at the moment, but I wanted to make sure I had a good plan in place before I started piecing this together because I don't want to get everything done only to figure out it doesn't work as I intended.

Thanks in advance for your input!
