BP-imitation scale simple verse composition challenge

I realize this is a long shot but here goes...

I have made my own BP-like (IE aimed at odd-harmonic-intensive timbre instruments and composed of fractions derived from odd harmonic partials) scale. And, to my ears at least (using a clarinet as a test instrument), there is no doubt my scale sounds significantly more stable, but I'm obviously aesthetically biased toward my scale.
--------
Anyhow Here's the challenge: compose a 6-chord progression + bass-line + lead melody + background melody in BP...basically "just" a full verse.
Then turn around and try to fit it to my scale (not necessarily hit around the same frequencies, but rather do whatever modifications on the original you need to make the version in my scale hit the intended mood of the version in the BP scale).

I would like to see the results of how far others can get so far as making my BP-imitation scale sound competitive with BP...and if it doesn't even get close then (well)...guess I just don't have a good mind for composing in BP and need much more practice (or have odd aesthetic preferences against BP).
'-----------------------
Here are the tones in my "Inverse BP" scale (note it only has 8-tones and not BP's 9 tones):

1/1
8/7
11/9
7/5
5/3
21/11
15/7
27/11
3/1 (tri-tave)

Have fun, Mike

I am confused.

Which BP are you referring to with 9 steps?

"Bohlen originally expressed the BP scale in both just intonation and
equal temperament. The tempered form, which divides the tritave into
thirteen equal steps, has become the most popular form."

>"Which BP are you referring to with 9 steps?"
In am referring to the diatonic BP scale from http://en.wikipedia.org/wiki/Bohlen%E2%80%93Pierce_scale.
The 13-tone BP of which you speak, I believe, is the entire BP temperament of which the scale is simply a subset.
So, of course, a temperament is not a scale...in the same way the standard 7-tone diatonic scale is different than the 12-tone 12TET temperament it fits under.

And again, so far as the composition challenge, the tones are

For >my< odd-harmonic timbre-based scale
1/1

8/7

11/9

7/5

5/3

21/11

15/7

27/11

3/1 (tri-tave)

For BP diatonic
1/1
25/21
9/7
7/5
5/3
9/5
15/7
7/3
25/9
3/1

Again, those are the two scales I want to compare in the challenge.
