Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Probabilistic latent semantic indexing (PLSI) represents documents of a collection as mixture proportions of latent topics, which are learned from the collection by an expectation maximization (EM) algorithm. New documents or queries need to be folded into the latent topic space by a simplified version of the EM-algorithm. During PLSI- Folding-in of a new document, the topic mixtures of the known documents are ignored. This may lead to a suboptimal model of the extended collection. Our new approach incorporates the topic mixtures of the known documents in a Bayesian way during folding- in. That knowledge is modeled as prior distribution over the topic simplex using a kernel density estimate of Dirichlet kernels.  demonstrate the advantages of the new Bayesian folding-in using real text data.
