a PLS regression

if there is a multivariate structure in your data it will extract it (PLS regression is available in several R packages, SAS, XLSTAT ...). But collecting more data would definitely help.With 11 cases you have multiple problems. The power of your test will be small. You may not be able to generalize to a larger population (a separate issue than power). Violations of regression assumptions will be more serve with so few cases.
